PNEUMATlC-DESPATCH-TUBE CARRIER.

SPEGIEICATION forming part of Letters Patent No. 690,894, dated January'7, 1902.. Application filed April 3, 1901. Serial No. 54,208. (Nomodel.)

To all whom, it may concern:

Be it known that I, ALBERT W. PEARSALL, a citizen of the United States,residing at lWIountVernomin the county of Westchester and State of NewYork, have invented new and useful Improvements inPneumatic-Despatch-Tube Carriers, of which the following is aspecification.

This invention relates to carriers or receptacles such as used fortransporting by pneumatic pressure; and the invention resides in thenovel features of construction set .forth in the following specificationand claims and illustrated in the annexed drawings, in v which- Figure 1is a sectional side elevation of the carrier. Fig. 2 is a sectionalong0c 0:, Fig. 1, showing the carrier closed. Fig. 3 is a section like Fig.2, showing the carrier open. Fig. 4 is a section along y Fig. 1, thecarrier being closed. Fig. 5 is a view like Fig. 4, the carrier beingopen.

The carrier is shown comprising two parts or sections, an outer shellbeing shown at a and an inner shell at (9. These receptacle parts havetheir walls partly cut away or open to form mouths, and when thereceptacle parts are turned so that their mouths coincide the carrier isopen, as seen in Figs. 3 and 5, to allow access to the interior.Rotating the receptacle parts with respect to one another so that themouths are carried away from one another causes closure of the carrier,as seen in Figs. 2 and 4, so that contents are secured or confinedtherein. The outer part a is shown formed open at one end and with abottom a at the other. The bottom is shown with a circular cut oropening placed eccentrically or with its center out of line with theaxis of part a, the outline of such circular eccentric out beingindicated at d in Figs. 4 and 5. This cut or seat (1 forms a bearing fora corresponding hub or shoulder part formed or placed eccentrically onthe head or disk e. As the head a is rotated in the eccentric bearing (Zit is carried from concentric position to eccentric and back againrelatively to the end 0 or to the axis of the part a. This head 6 isfixed to or forms part of the end f of the inner part b. Screws or bolts9 can be made to secure the parts e and f to'one another, and suchfastenings g can also serve for securing the packing or felt h in place.This felt h, it is thus noticed, rotates or swivels with part1) and canrotate independently of part a or while part dis grasped or heldstationary. The other endt of part b is shown provided with aneccentrically-located hole or bearing for a pivot or gudgeon Z on heador disk on, forming a plug for or one end of part a. A fastening orscrews n are shown securing the parts am to one another, and this headon is shown with packing or felt 0 suitably bolted or secured thereto.The carrier parts a and I] thus swivel with respect to one another orcan be rotated from and to concentric position and eccentric position,as shown, respectively, in Figs. 2 and 3 or by comparing Figs. 4. and 5.In other words, felt 7t rotatingwith part b and felt 0 rotating withpart a and said felts being grasped and turned or one felt given a twistwith respect to the other,the parts ab are moved to closed orto openposition, as the case may be. When the parts or felts are inconcentricposition or the carrier is closed and the felts made to snuglyfit or pack to the despatch-tube, into which the carrier is introduced,any tendency to open or of the felts to move to eccentric position iscounteracted or prevented by the clasp or fit of the tube about thefelts. The carrier can thus not open accidentally or intransit,and suchcontents as coin or change can be safely intrusted thereto. Even shouldthe felts be worn or somewhat loose the lap of the parts a b when closedcan be sufficient (see Fig. 2) to avoid an opening or slit resultingeven in case of some loose ness or play of the felts with respect to oneanother while the carrier is in the tube. A change-carriermade on thisplan can be easily closed or manipulated with one hand, the part I)being swiveled or turned by the thumb until in the position shown inFig. 2.

This carrier, it has been found, is not apt to lose its shape or tosuffer from binding of its parts in consequence of the impact when ondelivery the felt it or 0 strikes a stop or arresting-point. The impactbeing taken up by both parts a and b, acting together, is so distributedthat no warping or loss of shape can occur. For example, the blow onfelt h ICO is taken up not only by the heads 6 and fol part b, but alsoby the head 0 of part a. Like- Wise a blow at felt 0 is taken up by theend of part awith the plug mand also by the end 2' of part b. In thisway the end or head of each part a or b is, as it were, braced orstrengthened in being backed by the other section I) or a. It can alsobe noted that while both parts a b clasp or contact with one anotherwhen closed, as seen in Fig. 2, the opening or eccentric movement of theparts causes one part to move or rotate away from the other, so that themovement is easy when opening or moving to the position shown in Fig. 8.When the carrier is open or the two mouths or cuts in the walls of partsa booincide, as seen in Fig. 5, the weight or bulk of the material ofthe two parts ct I) rests opposite the openings or mouths, so that thecarrier normally rests with the openportions facing upward. The dangerof spilling, upsetting, or rolling of an open carrier is thus avoided,and as a felt it or o is moved eccentrically to such an extent as tocarry a point of its circumference beyond the boundary of part a or I)such projecting point of the felt presents a stop or obstacle against anopen carrier rolling, for example, off a table. he mouth or cut in thewallorside of outer part 2' is of course of such size, both lengthwiseas well as crosswise, as to allow for the eccentric movement of theinner part in opening and closing. The arrows in Figs. 2 and 4 indicatethe direction of motion of the outer shell for opening. The arrows inFigs. 3 and 5 indicate the closing swing or direction of such outershell.

What I claim as new, and by Letters Patent, is-

1. A carrier or receptacle comprising inner and outer sections pivotedeccentrically with respect to one another substantially as described.

2. A carrier or receptacle comprisinginner and outer sections made topivot or rotate ecdesire to secure eentrically With respect to oneanother each provided with a packing or felt part being made to rotateor swivel with its respective part substantially as described.

3. A carrier or receptacle comprising inner and outer sections pivotedeccentrically with respect to oneanother, each section being providedwith an end felt or packing and having such end braced or backed by theother section substantially as described.

4. A carrier or receptacle comprising two parts operating one within theother pivoted eccentrically and made to move to a concentric positionwhen closed and to move to an eccentric position when open substantiallyas described.

5. A carrier or receptacle comprising two eccentrically-pivoted parts orsections, each part having a mouth or cut-away part in its wall and saidmouths being made to coincide for opening the carrier and for bringingthe weight of material of the same opposite the coinciding mouths forholding the open carrier in position with its mouth upward substantiallyas described.

6. A carrier or receptacle comprising two sections operating one withinthe other each provided with a felt or packing, and pivotedeccentrically to one another so that on swiveling the parts to open thecarrier a point onthe circumference of the felt of one part is made toproject beyond the boundary of the other part substantially asdescribed.

7. A carrier or receptacle comprising parts placed one within the otherand having cuts or openings in their walls or sides, the inner part whenopening and closing being made to swivel or move eccentrically withregard to the outer part and said outer part havingits mouth of suchsize as to allow such eccentric movement of the inner part substantiallyas described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
